TOY SUBMARI EQ Specification of Letters Patent. Patented July 30 v 1918.

Application filed October 10, 1917. Serial No. 195,725.

To all whom it may concern:

Be it known that I, WENDELL I-I. CALD- nncx, a citizen of the United States, and

resident of Des Moines, in the county of Folk and State of Iowa, have invented a certain new and useful Toy Submarine, of which the following is a specification.

The object of my invention is to provide a toy submarine of'simple, durable and inexpensive construction.

Moreparticularly it is my obj ect to pro.

vide a toy submarine having a body adapted to float readily in water, and'having an up-- right vertical keel for causing the submarine to travel ahead steadily andhavinglaterally extending planes or wings, and having a divingplane or forwardly and downwardly extending wing for causing the-device to movedownwardly in the water when the propeller is operated. I 1

A further object is to provide such a de vice having a suitably mounted propeller,

with simple and inexpensive means for imparting rotation to the propeller in the water.

With these and otherobjects in view my invention consists in the-construction, arrangement and combination ofthe various parts of the device, whereby the objects con templated are attained, as hereinafter more fully set forth, pointed out; inmy claims,

the accompanying drawand illustrated in ings, in which:

Figure 1 shows a side elevation of a toy submarine embodying my invention.

Fig. 2 shows a front elevation of the same. Fig. 3 shows a transverse, vertical, sectional view taken on the line 33 of Fig. 1'.

In the accompanying, drawings, I have used the reference numeral 10 to indicate generally the body of my improved toy submarine which has substantially the shape of a cylinder; slightly tapered toward its rear end and tapered to a point at 11 at its;

forward end.

The body 10 may be made of wood or any suitable'material, and in any suitable way, so that it will readily'fl'oat in water. 7

Mounted in the lower part of the body 10, and extending fromfr'ontjto rear. thereof, is a plate 12, which aboveiand in front of the wings hereinafter mentioned, forms a keel. The plate 12 is provided at its lower forward corner with an opening 13 to which a string or the like may be attached. 7

On opposite sides of theplate 12 are latperiscope.

erally' extendingwings 14", which-are in clined from the rearend of the submarine forwardly and downwardly, as shown. in Fig. :1, and are; also curved from-the plate 12 upwardly and outwardly, as shown-in Fig.3.

The wings 14 are moved downwardly and forwardly at l5 at: their for-ward ends, and

may at theirw forward-ends: be formed integral with each other if desired At their, adjacent edges, during the'greater portion of their 'lengthfiand exceptlat their forward ends, thewings are provided with flat parallelvdownwardly extending flanges:

. 16 forming akeel. The-flangesldhave at their rears ends downward: extensions 17-, and provided at their lower edges with:

spaced, downwardly extending. bearings 18;

Mounted in thebearings 18 is a shore shaft '19'having on its forward end a hook 20,.a'ndron itsrear. end spaced from the rearward bearing 18,'a propeller 21. I

Mounted on the shaft 19 between the pro- 2 wardly and: forwardly extending. portion 15,

of the; wings 1 L is-provided with a central. opening 23 which permits .water. to pass throughduring the progress: of the v.sub- -marine and assists .in causing the submarine peller:21-and tthe rearward-bearing 18: is a '2 suitable. bushing or the ::like, which may. consist of. an'ordinary-bead22; The down-' to travel forwardly steadily and withu i,

causethe submarine, during the rotation'of the propeller, to movev downwardly in the water for a certain distance, and thereafter the submarine will travel horizontally in the water. When the motion of the propeller stops, the submarine will gradually float to the top, where the periscope 27 will project out of the water.

The arrangement of the wings 14 inclined downwardly slightly from their rear ends, and with the sharpened inclination at their forward ends is such as to cause the submarine to move downwardly in the water when the submarine is placed in the water at the surface.

The plate 12 and the flanges 16 form a keel and cause the submarine to travel straight forwardly.

The hole 23, I find also assists in causing the proper steady movement of the submarine.

The parts are of very simple construction, and the entire device can be made rapidly and at a small expense.

It will be noted that the plate 12 may be placed in a saw kerf in the body 10, where the body 10 is made of wood, and that the wings may be made of a single piece of metal split along a central line, except at their forward end, and bent to the proper shape.

It should be mentioned in'this connection that the wings 1d are narrower from side to side at their rear end, than at the central portion. It should be noted also that the portion 15 is tapered from its side toward the front.

It may wings 14. is of considerable importance.

It will be noticed that they come together and are tapered, so that such forward ends incline downwardly and forwardly from the body of the submarine, and also are tapered toward a curved nose in front. struction is important insomuch as the submarine is usually used in a bath tub, tub or tank with a curved wall. When the subma rine travels along under the water the nose or front of the wings 14: strikes the wall and beingcurved and flared, tends to deflect the submarine and turn it to a path along side the wall where it can travel properly. Where the submarine keeps on going and strikes the bottom, the front ends 15 of the wings 1d form a nose, which touches the bot tom of the tub or the like, and this causes the submarine to come down to an even keel or horizontal position whereupon it will travel along the bottom in that position.

Some changes may be made in the construction and arrangement of the parts of my improved submarine, without departing from the essential features and purposes of my invention, and it is my intention to cover by the patent to be issued upon my application, any modified forms of structure or be mentioned in this connectionthat the shape of the forward ends of the This conuse of mechanical equivalents, which may be reasonably included within the scope of my claims.

I claim as my invention:

1. In a toy submarine, a body adapted to float in water, having a tapered front end, a plate secured to said body at the forward part thereof, and extending from the lower end thereof rearwardly, side wings extending from the forward portion of said body at the lower part thereof rearwardly and slightly upwardly, said side wings being also curved from the lower central portion of said body upwardly and laterally, a downwardly inclined member at the for ward end of said side wings forming a diving plane, a keel below said side wings and below the center of said body, a shaft at the lower portion of said device, a pro peller thereon, a hook member on said diving plane, and a resilient device connected with said hook member and with said shaft.

In a toy submarine, a body adapted to float in water, having a'tapered front end, side wings extending laterally and upwardly from the central lower part. of said body, and inclined from their forward ends upwardly and rearwardly, a central, vertical plate extending downwardly from the for.- ward portion of said body, a diving plane curved downwardly from the forward ends of said side wings, and tapered toward its forward end, said diving plane having a central opening.

3. In a toy submarine, a body adapted to float in water, having a tapered front end, side wings extending laterally and upwardly from the central lower part of said body,
